Can I use ImageMap and require editors to login in mediawiki?

Question

I can't edit a page using the imagemap tag when logged in. This is for a mediawiki installation where all editors must be logged in.

Page is at http://mediawiki.owenks.uk/wiki/index.php?title=ImageMapPage

If I change the permissions and allow all users to edit, then I can save the page. But if I change permissions back to $wgGroupPermissions['*']['edit'] = false; then login and try to edit the page, I get a blank screen after hitting "Save Page".

I tried to ask on the mediawiki help site but was unable to post.

Any suggestions?

Answer 1

Was nothing to do with ImageMap. Was a conflict with GraphViz extension. Removing the GraphViz extension put everything back to normal.
